CIRCE2 is a computer code for modeling the optical performance of three-dimensional dish-type and trough-type solar energy concentrators (possibly made up of several separate reflecting surfaces or "facets" of various curvatures and projected shapes). Statistical methods are used to evaluate the directional distribution of reflected rays from any given point on the conventrator. Given concentrator and receiver geometries, sunshape (angular distribution of incident rays from the sun), and concentrator imperfections such as surface roughness and random deviation in slope, the code predicts the flux spatio-angular distribution and total power incident upon the flat or volumetric receiver. Great freedom exists in the variety of concentrator and receiver configurations that can be modeled. Additionally, provisions for shading, blocking, and receiver aperturing are included. DEKGEN2 is a preprocessor designed to facilitate input of sun models and concentrator geometry and surface imperfections.
